Stop motion animation is pretty alright but it seems you don't have much of a story to tell. Camerawork is very shaky. When it comes to voice acting it's hard to tell who's saying what since their voices are the same, you could put more effort into making them distinct. You haven't put any effort in scenography, there are no props, no fake environment, you haven't cleaned up everyday objects for the shots. If we are to believe they're not just toys there's nothing indicating that they aren't.
